2、what is NRZ data

In telecommunication, a non-return-to-zero (NRZ) line code is a binary code in which "1's" are represented by one significant condition and "0's" are represented by the other significant condition, with no other neutral or rest condition. The pulses have more energy than a RZ code, but it does not have a rest state, which means a synchronization signal must also be sent alongside the code.

For a given data signaling rate, i.e., bit rate, the NRZ code requires only half the bandwidth required by the Manchester code.

When used to represent data in an asynchronous communication scheme, the absence of a neutral state requires other mechanisms for data recovery, to replace methods used for error detection when using synchronization information when a separate clock signal is available.

NRZ-Level itself is not a synchronous system but rather an encoding that can be used in either a synchronous or asynchronous transmission environment, that is, with or without an explicit clock signal involved. Because of this, it is not strictly necessary to discuss how the NRZ-Level encoding acts "on a clock edge" or "during a clock cycle" since all transitions happen in the given amount of time representing the actual or implied integral clock cycle. The real question is that of sampling--the high or low state will be received correctly provided the transmission line has stabilized for that bit when the physical line level is sampled at the receiving end.

However, it is handy to see NRZ transitions as happening on the trailing (falling) clock edge in order to compare NRZ-Level to other encoding methods, such as the mentioned Manchester code, which requires clock edge information (is the XOR of the clock and NRZ, actually) and to see the difference between NRZ-Mark and NRZ-Inverted.
